OBJECTIVE:To investigate the effects of simvastatin on neurologic function and prognosis of patients with cere-bral infraction. METHODS:A total of 82 patients with cerebral infarction selected from our hospital during Jan. 2015 to Jul. 2016 were divided into observation group and control group according to random number table,with 41 cases in each group. Control group received routine thrombolytic therapy and Aspirin enteric-coated tablets 100 mg orally,qd. Observation group was additional-ly given Simvastatin tablets 10 mg,qd,on the basis of control group. After 1 month of treatment,prognosis,ADE as well as NI-HSS scores before and after treatment were compared between 2 groups. Multiple factor Logistic regression analysis was conducted for clinical information of patients. RESULTS:The excellent rate of prognosis in observation group was 80.49％,which was signifi-cantly higher than 68.29％,with statistical significance(P<0.05). The incidence of intracranial and extracranial vascular stenosis, brain-heart syndrome and death in observation group were 36.59％,19.51％,0,which were significantly lower than 46.34％, 36.59％,7.32％ of control group,with statistical significance(P<0.05). At admission,there was no statistical significance in NI-HSS scores between 2 groups(P>0.05). After 1 month of treatment,NIHSS scores of 2 groups were decreased significantly,and the observation group was significantly lower than the control group,with statistical significance(P<0.05). Age >65 years,NI-HSS score <4 points at admission,combined diabetes,non-use of statins were independent risk factors which affected the survival of patients with cerebral infarction(P<0.05). CONCLUSIONS:Simvastatin can significantly improve the neurologic function and prognosis of patients with cerebral infarction,and reduce the incidence of ADE. Non-use of statins is an independent risk factor which affects the survival of patients.

Objective To study the effect and mechanism of antisense oligodeoxynucleotides (ASONs) inhibiting hepatitis B virus (HBV) expression. Methods We designed and synthesized antisense oligodeoxynucleotides directly against HBV PreS 2 gene and noncomplementary sequence control. 2.2.15 cells were chosen as cell model. Inhibitory effect of ASONs on HBV gene expression were assayed by ELISA. Cell apoptosis and proliferation were detected by Fascan Flow Cell Cytometer. Effect of ASONs on cell metabolism was detected by radioimmunoassay (RIA) and MTT assay. Results ASONs were able to effectively inhibit HBV expression. Their inhibitory rates of HBsAg and HBeAg were 66% and 91%, respectively. Noncomplementary sequence control group (both inhibitory rates were 11%) was not able to inhibit HBV expression. ASON might induce host cell apoptosis. Cell apoptosis rates on 3rd and 6th day were 6.10% and 6.43%, respectively. Proliferation index were 37% and 36%, respectively. Results of RIA and MTT showed that ASON had not cytoxicity on host cell. Conclusions Not only are ASON able to inhibit HBV gene expression with sequence specific but also clear HBV in the way of apoptosis.

Objective To analyze the clinical data and features of malignant hyperthermia (MH) in Mainland China and address the problems associated with diagnosis and treatment of MH.Methods Thirty-four cases of MH which occurred in Mainland China from January 1978 to March 2004 were reviewed and analyzed. Results MH syndrome occurred more frequently in adolescents with more males than females and developed very often during oral surgery ( especially cleft lip and palate repair), orthopedic surgery and pediatric surgery for congenital anomalies. The main clinical manifestations included hypercapnia, high body temperature and muscle rigidity. In most cases diagnosis of MH was made based on clinical manifestations only without'in vitro contracture test the golden standard for diagnosis of MH. No specific treatment was available and no epidemiological study was done. Conclusion The report of MH has been increasing recently in Mainland China. Studies on MH should be intensified by establishing the standard of laboratory diagnosis of MH.

Objective To investigate the efficacy of acupuncture combined with doctor-nurse cooperation mode on stroke-associated pneumonia in patients with acute stroke. Methods 67 patients of acute stroke within 1 week in our hospital from March, 2013 to January, 2015 were randomly divided into control group (n=35) and treatment group (n=32). Both groups received neurological routine treatment and systematic rehabilitation training by professional physiotherapists under general nursing mode. The treatment group received acupuncture treatment under doctor-nurse cooperation mode additionally. Incidence of stroke-associated pneumonia, swallow function and aspiration rate were recorded. Results Compared with the control group, the incidence of stroke-associated pneumonia significantly decreased in the treat-ment group after treatment (χ2=4.615, P=0.032). The retention volume of epiglottic vallecula and pyriform sinus (tdilute barium=21.01, tthick barium=19.85), the duration of pharynx period (tdilute barium=17.03, tthick barium=13.68), and the start time of pharynx period (tdilute barium=19.63, tthick barium=17.86) were less in the treatment group than in the control group (P<0.05). In the test of dilute barium, the aspiration rate was lower in the treatment group than in the control group (χ2=4.03, P=0.044), however, there was no significant difference between 2 groups in the test of thick bari-um and solid food (P>0.05). Conclusion Acupuncture combined doctor-nurse cooperation mode may decrease the rates of aspiration and stroke-associated pneumonia in acute stroke patients through improving their swallow function.

Objective To screen the ryanodine receptor type 1(RYR1)gene in a Chinese pedigree with malignant hyperthermia(MH).Methods Total genome was extracted conventionally from peripheral leucocytes of the prohand and the other members of the family.In order to detect mutations in the RYR1 gene,part exons were amplified by polymerase chain reaction(PCR)and then subjected tO automatic DNA sequencing.The detected mumfion in the gene was confirmed in the preband and the other members of the family using Fok Ⅰ restriction analysis.Results DNA sequencing of PCR-amplified fragments of the pwband revealed c.6724C＞T (P.T2206M),a recurrent missense mutation which had been detected in Caucasian MH cages.Restriction analysis of all available family members showed that one daughter and one son of the 4 children of the proband were the missense mutation carriers,indicating that they were MH-susceptible individuals.Conclusion The Chinese susceptible to MH carries the simile RYR1 gene mutation to the Caucasians susceptible to MH.

The peroxisome prolifrator-activated receptors(PPARs)? and ? constitute a subfamily of nuclear receptors. PPAR? has been shown to be activat ed by the hypolipidemic drugs of the fibrate class; While the antidiabetic TZD a re synthetic ligands for PPAR?. Upon binding and activation by their ligands, t hey regulate the transcription of numerous genes involving lipid metabolism and insulin resistance. The research indicated that PPAR? also plays a key role in lipid metabolism. PPARs therefore constitute interesting targets for the develop ment of single and dual agonists useful in the treatment of obesity and type 2 d iabetes.

Objective To study the characteristics of cerebral glucose metabolism in adults with hypoxic-ischemic encephalopathy (HIE) using positron emission tomography (PET) and statistical parameter mapping (SPM), and evaluate the degree of the cerebral glucose metabolism damaged. Methods 26 HIE patients and 20 healthy controls received 18F-FDG PET imaging. The scope and degree of the brain radioactivity decrease were observed with visual analysis. The three-dimensional projection images and the KE value were obtained by SPM analysis. Results The glucose metabolic decrease in HIE was primarily bilaterally. The bilateral basal ganglia and thalamus metabolism decreased most obviously. The brain cortical lobes varied degrees of metabolic decrease according to the order from high to low was the frontal, occipital, parietal and temporal lobes. The basal ganglia and thalamus were taken as the important target area of the evaluation of damage degree, the degree of damage of HIE was divided into Level Ⅰ(mild), Level Ⅱ(moderate) and Level Ⅲ (severe) combined with cortex damage. Conclusion The basal ganglia and thalamus are the target areas of metabolic damage, the classification combined with brain cortex damage degree and scope can be used to guide the clinical treatment and prognosis evaluation.

Objective To observe the effect of acupuncture combined with moxibustion on heart rate variability (HRV) in patients with post-stroke depression. Methods 120 patients were divided into control group (n=60) and treatment group (n=60). Both groups took fluoxetine and accepted acupuncture therapy, and the treatment group accepted moxibustion additionally. Hamilton Depression Rating Scale-17 (HAMD-17) and the change of HRV were compared before and after treatment. Results The score of HAMD was lower, and the reductive ratio was higher in the treatment group than in the control group (P<0.05). The standard deviation of the mean of qualified normal sinus interval (SDNN) and standard deviation of sequential five-minute R-R interval means (SDANN) increased in both groups after treatment (P< 0.05), and were higher in the treatment group than in the control group (P<0.05). The root mean square differences of successive R-R intervals (RMSSD) and percentage of differences between adjacent normal sinus intervals greater than 50 ms (PNN50) decreased in both groups after treatment (P<0.05), and were lower in the treatment group than in the control group (P<0.05). The low frequency (LF), high frequency (HF) and LF/HF were higher in both groups after treatment (P<0.05), and were higher in the treatment group than in the control group (P< 0.05). Conclusion Acupuncture combined with moxibustion therapy can better adjust the function of autonomic nerve and reduce depression in patients with post-stroke depression.
